A state can transition to itself: make transition and a second click on the same state connects a self transition, taking it fires On state exited and then On state entered every time, for local and global machines, while Set state into the current state stays silent as before; only states may connect to themselves, every other node is still refused, one self transition per state; the loop is drawn over the middle of the top edge with its arrow pointing down and its name at the apex, the preview already shows it while armed, and the inspector lists it once under Transitions out; new test hook transitionLabelAt, e2e 26e5 (#163)

A state change is something the graph can react to, so the machine announces it (#53, #54, #55, #57)
game-maker / suite (push) Successful in 10m58s
Four issues that all reach for the same line: how the current state is read and written. Splitting them into four commits would mean four states of the tree that do not compile, so they arrive together. #55 start state — the machine asset carries an optional `start` holding a State node's id. Right-click a state to set or remove it, a ring in the node's title says which one it is. A dead id (the state was deleted) reads as "no start", so nothing has to clean up after a deletion. #53 entered/exited — `On state entered` and `On state exited`, one exec output per state. Every change now goes through a single `setState` that reports it; BehaviorSystem delivers it after the exec flow that caused it, `exited` of the old before `entered` of the new, round after round until the queue is empty, with a cap that stops a ping-pong graph with an endless-loop error. A local machine tells the instance that switched, a global one tells every instance holding a matching event node. The start state fires `entered` too: per instance for a local machine, once per run for a global one. #57 reading — `Current state` with `name` for showing and `id` for comparing, `Is in state` with one boolean per state. Neither has a `run`, so `read` learned `def` and `lookup`, and the catalog test knows this third kind of node. #54 seeing it — during a run the state machine tab marks every state some instance is holding faintly, and the one held by the selected scene object's instance strongly.

A shared value belongs to the run, so a declaration carries its scope (#91)
A variable or a state machine declared `global` keeps one value for the whole run instead of one per behavior instance. The scope sits on the declaration -- `PropertyDef.scope` and `StateMachineAsset.scope`, both optional, absence meaning `local` -- and `local` is never written, so every project made before this saves back unchanged. **The name is the key.** Two behaviors declaring a global `score` mean one variable; a behavior declaring `score` locally keeps its own. Kinds that disagree about one global name stop the run before it starts, with the two behaviors named; starting values that disagree are a warning on the behavior that declares it, and the first declaration wins (`globalConflicts`). The runtime needs no redirection layer. A global variable falls out of `schemaForObject`, so it never reaches `entity.props` -- and then the whole rule is "whoever declares the name takes their own value" (`graph/sharedState.ts`). The `Variables` node is untouched and stays transparent: switching a variable to global breaks no existing graph, because `GraphInterpreter.readAll` builds a fresh object per read anyway and only asks `port.key in all`. That same cut answers the inspector. A shared value has no owner, so the placed object shows no row for it and can hold no override -- `SetVariableScopeCommand` takes the deviations that were there and undo gives them back. Both places say it in words rather than leaving a glyph to be guessed: the declaration explains the mark below the list, and the placed object names the variable it no longer holds instead of claiming the behavior declares none -- which is what it said before, untruthfully. Screenshots of the e2e run turned that up; no check had been looking at it. `SharedState` hangs off `NodeContext`, is built in `BehaviorSystem.start()` from the *declarations* rather than from any instance (a global variable exists before its behavior is placed), and is thrown away with the run: nothing is written back, not even in the editor run. `GraphInterpreter.call` passes it on through `...ctx` while nested calls keep getting fresh local variables, which is why `program.defaults` is stripped of global keys. Two traps this hit. `defSignature`/`assetSignature` have to carry the scope or the inspector does not rebuild after the switch -- and a state machine has no rows at all, so its scope is appended to the signature by hand. And the object inspector does not go through `schemaForObject` for behaviors, it reads `asset.variables` directly; filtering in one place was not enough, and no unit test covered that path. The e2e caught it (`global: true` where false belonged), and the rule now lives in one named function, `objectRows`. Scopes `object` and `scene` are deliberately not built. The object case already has a route (`Object by name` -> `Properties`), and a run knows exactly one scene, so `scene` would be indistinguishable from `global` until #39 exists. Closes #59: a machine's scope is a word on the machine asset, not a setting per `Set state` node, so the same machine cannot live in two places at once.

A transition carries a name, so a state needs no visible port (#52)
game-maker / suite (push) Successful in 10m22s
A state keeps its `in`/`out` exec pins in the model and the editor never draws
them. That is the whole trick: connecting, undo, deleting a state and saving all
keep working untouched, because `normalizeGraph` filters nodes and never edges,
and no edge ever checks its port key against a NodeDef. Only two places change --
`NodeView.redraw` stops drawing the row, and `portAt` refuses to hand one out, so
an invisible pin cannot be grabbed either.
Transitions are drawn by right-clicking a state, `Make transition`, then clicking
the target. The armed mode takes the same shape as a live drag, so the existing
preview draws it with no second code path, and it dies with Escape, a click on
empty canvas or a switch to another asset.
Removing the pins removed the only handle a transition had: edges have no
hit-test anywhere, and the pin right-click was the sole route to Disconnect.
The inspector's TRANSITIONS OUT / TRANSITIONS IN lists are therefore not a
convenience, they are the delete path.
`GraphEdge` gained an optional `label`, which `normalizeGraph` has to pass
through explicitly or a saved name is dropped on load. `State transition`
replaces `Next state`: it takes the machine on an input port and the name from a
picker, and resolves against the *current* state. Names are deliberately not
unique across a machine -- two states may both have an `alarm` -- so a node named
`alarm` moves whichever state has one, and an empty name follows the single
unnamed edge.
The geometry moved to a Pixi-free `transitions.ts`: a gap to the box border, and
a fan that puts a pair of opposite edges beside each other instead of on top of
each other. Keeping it as plain maths is what let a screenshot bug become a unit
test -- an earlier pin-to-pin line ran under the target node and took its
arrowhead with it, because `nodeLayer` sits above `edgeLayer`.
One limit stands and is not fixed here: `ConnectCommand` rejects a second edge
between the same two states ("Already connected"), because every transition
hangs off the same two ports. With names, `A --alarm--> B` beside
`A --seen--> B` is a sensible pair, so this is worth its own issue.
